i just put a 3/4 space under my front springs on my 00 trailboss what a improvement should work for othere polaris atv i made them out of thread adjuster from polaris extra 12 rear spring adjuster get at any polaris dealer then grind of the top ring so it's flat cheap and works later

 

What exactly does this do for you????

 

it firm up the suspension

 

They sell a kit in dennis kirk like that but it bet your idea is allot cheaper the 150 bucks. Does it help the dive when hitting the brakes hard?

 

it helps all round

 

On the Sportsman, you will probaly like the heavy duty springs better. It makes the rider better (in my opinion), and it handles better without as much sway and dive. We only have them on the front though.
